This is a moderately large protoconch, with shallow, coarse pitted sculpture over the entire shell, giving it a grainy appearance under the light microscope. The shell is dorsoventrally flattened, so it is usually found either with the aperture facing down or lying at an angle with the aperture visible. The posterior portion of the aperture flares out from the body, forming a deep indentation on both sides. The posterior of the shell is smoothly rounded.
